The Canadian Warbler is seldom noted in the Cambridge Region excepting 

 during migration, when it usually appears at nearly the same dates and in about 

 the same numbers as the Wilson's Blackcap. The spring flight sometimes 

 begins as early as the 9th or lOth of May, but ordinarily not before the 12th or 

 15th, while the movement is seldom at its height before the 20th and often not 

 until the 25th or 26th. Most of the birds pass further north before the close 

 of May, but a few linger into the first week of June. Like the Blackcaps they 

 are nearly always met with singly, and usually in damp thickets, although they 

 sometimes visit our city gardens and they are occasionally seen in upland woods 

 especially where there is an undergrowth of bushes or of young pines. It is prob- 

 able that the return migration passes southward by some more inland route, for 

 the Canadian Warbler is comparatively seldom found in eastern Massachusetts 

 in autumn. Indeed I have met with it only thrice at this season — on August 

 25, September i and September 2, 1884. On each of these occasions a young 

 bird was taken among red cedars on a hilltop just to the westward of Mount 

 Auburn. Mr. Walter Fa.xon has given me a note relating to a Canadian War- 

 bler which he saw in Belmont on September 18, 1889.
